libdl: search for ELF_RTYPE_CLASS_DLSYM in dlsym()
On FDPIC platforms, functions are passed by function descriptor, not by pointers. If you don't specify ELF_RTYPE_CLASS_DLSYM when calling _dl_find_hash() the return value from dlsym() will be a pointer not a function descriptor, crashing the program. The bug was introduced when TLS support was added in 534661b91c98492995274c364c8177c45efc63db Closes bug#3433 Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
